Mathew wrote a review of Scarpa Booster Climbing Shoe - Discontinued Vibram XS Grip on March 7, 2012
In my opinion I think there are much better shoes out there. I love Scarpa, but it seems like they were intentionally trying to make the heel cups on the Boosters 5 sizes too big... I still just don't get why the heels are so big! If you want to stick with Scarpa then I would suggest trying the Vapor Vs... But! again in my opinion, I am still in love with La Sportiva's Solutions.
